Adobe After Effects CS4 Essential Training: Luminance Correction

By Chad Perkins

In After Effects CS4 Essential Training, Chad Perkins teaches fundamental motion graphics design techniques from the ground up. He shows how to gather video, audio, and graphical source materials into layered compositions, make edits and adjustments, then bring it all to life with a powerful array of visual effects and animation techniques. These skills are demonstrated in a series of increasingly intricate projects, from creating a galaxy to building a fantasy battle scene. Chad also demonstrates workflows for keying and compositing, shows how to integrate with other applications, shares useful tips and secrets, and much more.

In this clip, host Chad Perkins looks at how to correct luminance, or brightness problems in your footage. He shows you the color corrections panel and discusses the auto levels and other auto effects, but also works in the levels effect, detailing the histogram which shows what is going on in your image, shadow areas, mid tones and highlights of the histogram.
